Use the following properties to enable HTML tags in tooltips:

  • ToolTipController.AllowHtmlText — for all regular and super tooltips managed by this controller. Assign the ToolTipController component to the control’s ToolTipController property.
  • BaseControl.AllowHtmlTextInToolTip — overrides the ToolTip Controller’s setting for a regular tooltip assigned to this control. To specify the tooltip’s content, use the BaseControl.ToolTip property.
  • SuperToolTip.AllowHtmlText — overrides the ToolTip Controller’s setting for a particular super tooltip. To assign a super tooltip to a control, use the BaseControl.SuperTip property.
  • ToolTipItem.AllowHtmlText — overrides the previous setting for a particular item (area) in a super tooltip. To specify the item’s content, use the ToolTipItem.Text property.


This example demonstrates how to enable HTML tags for the SimpleButton and TextEdit controls.

toolTipController1.AllowHtmlText = true;
simpleButton1.ToolTipController = toolTipController1;
textEdit1.ToolTipController = toolTipController1;
simpleButton1.ToolTip = "I\'ve agree to the <>terms and conditions</href>.<br/>I want to <b>subscribe</b> to the newsletter.";
textEdit1.ToolTip = "Enter your <b>valid</b> e-mail address.";

private void toolTipController1_HyperlinkClick(object sender, HyperlinkClickEventArgs e) {
    // Handle a click on a hyperlink displayed in a tooltip.
